Branch order
the number of bifurcations between an axonal or dendritic section and the soma. Branch order is denoted by °. For e.g., 1° refers to the first dendritic branch originating from the soma or the main apical dendrite
Path distance
the distance between a given section and the soma measured along the axon or dendrites
Resting membrane potential (Vm)
the membrane potential (in mV) of a single neuron when potential (Vm) electrically inert or in resting state
Membrane time constant (τm)
the time taken (in ms) for the neuronal membrane to charge or discharge
Input resistance (Rin)
is given by Ohm's law from the difference in membrane potential of a single neuron at the point of a current injection to after it has reached a steady state (Rin=∆V/∆I MΩ)
